NAIL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,544, dated October 6. 1885.

Application filed October 15, 1884. Serial No. 145,544. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANKLIN A. GLEASON, a resident of Brooklyn, in the county of Kings and State of New York, have invented an Iniproved Nail-Machine, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure 1 is a plan or top view of my improved naitmachine. Fig. 2 is a side elevation of the same. Figs. 3 and 4 are detail views hereinafter more fully referred to. Fig. 5 is a top view of the mechanism for heading the nails. Fig. 6 is a vertical cross-section of the machine on the line 0 c, Fig. 5. Fig. 7 is a detail cross-section of the eccentric and its connections on the longitudinal shaft of the machine. Fig. 8 is a top view, on an enlarged scale, of the clutch on said longitudinal shaft. Fig. 9 is a transverse section on the line k is, Fig. 8, and Fig. 9 a face view of one of the clutch-disks. Fig. 10 is a top view of part of the nipper-slide and its connections. Fig. 11 is aside View of the same, and Fig. 12 a detail crosssection on the line c is, Fig. 11.

This invention relates to certain improvements in nail-machines, part of which are improvements on the machine which is described in Letters Patent No. 181,258, which were granted to me August 22, 1876.

The object of the invention is, first, to so arrange the machine that, if parts thereof should become clogged by scraps of iron or other obstructions, the continued operation of the machine will not cause it to become Wrenched out of shape or broken.

Another object is to insure a certain connection between the nipper-slide and the wheel, which, when turned by the action of the nip per-slide, will affect the position of the clutch and the movements of the vibrator.

Another object is to impart to the headers a rectilinear instead of a curvilinear motion.

The invention consists, first, in a new construction of clutch, the same having a pivoted pawl, which is hung in a spring-ring forming part of the clutch, as hereinafter described. By this arrangement the clutch can be made inoperative without breaking any parts, if the machine is clogged by obstructions.

The invention consists, secondly, in connecting the eccentric on the longitudinal shaft of the machine by a yielding connection with the elbow to which it is joined, so that if parts of the machine should be obstructed this yielding connection will prevent breakage.

The invention consists, thirdly, in combining with the nipper-slide a certain lever by which the ratchet-wheel is caused to be turned, which lever is to take the place of the slide 9 9 that is described in Letters Patent N 0. 181,258, and which insures a definite connection between the nipper-slide and the ratchetwheel-moving devices in lieu of the uncertain connection described in said patent-that is to say, in the former patent, if the motions of the vibrator were insufficient, the slide 9 9 was liable to fail in making a proper connection with the T-lever 10.

The fourth part of the invention consists in combining one or more horizontally-sliding headers with vibrating heading-levers, and other devices hereinafter described, whereby the headers will receive a rectilinear instead of the curvilinear motion heretofore used in such machines.

I will first describe the clutch mechanism, which constitutes the first part of my invention.

In the drawings, the letter A represents the longitudinal shaft of the machine, which is substantially the same shaft as the shaft A of Patent No. 181,258. This shaft A carries the clutch C, that is moved against the pinion d by means of the lever j, whenever said lever is moved by the elbow 4, the said elbow being moved at proper intervals by the ratchetwheel 1 2 3.

The parts thus far enumerated are substantially the same in general arrangement and in object of operation as the parts similarly marked in said Patent No. 181,258; but the clutch 0, according to my present invention, is of peculiar construction-that is to say, the body of the clutch is made of two ringshaped parts, a and I), (see Fig. 8,) which two rings are united by a spring, f, which spring is firmly fastened to the part b, and bears against a hook, g, on the part a. In the part a is pivoted the catch or pawl, 71, which constitutes the engaging projection of the clutch for taking hold of the hook Z that projects from the loose pinion d. Whenever the parts operate normally, the clutch being crowded by means of the lever or carrier j against the loose pinion d, its pawl h will, engaging with the projection Z, cause the pinion d to be revolved, and this pinion will then actuate. the platecarriers in the manner substantially described in my former patent; but if the plate'carriers should be obstructed by some plate being out of position, or by a scrap of iron or otherwise, so that the pinion (I cannot possi- IO bly be revolved, the parts of the machine will nevertheless not be broken, because in that case the spring f will allow the pawl h to be crowded into the recess of the ring a, within which said pawl is pivoted, causing the tail of the pawl to clear the projection m, against which normally it finds its support, so that now, when the pawl has cleared such projection it will become free to enter into the recess and to be carried out of the way of the projection Z, thus preventing the pinion being turned. In other Words, the clutch being made in two parts, which are united with sufticient rigidity by the spring f, but yet permitted to turn on one another, the pawl, which is pivoted in one of these parts co and held stiff by the projection m of the other part normally, will, when the pinion is definitely obstructed, lose its support an and enter the recess in the ring a, so as to prevent the clutch 3O biting the pinion.

5 is fastened to the shaft A.

is used in lieu of the feather on the shaft, which is impracticable where the clutch is made of the two rings 12 and a.

It is evident that instead of having the tongue 0 on the ring I), it may as well be made.

- to project from the collar einto a recess of the ring I).

I will now describe the second part of my invention, which refers to the connection of the eccentric on the shaft A with the'elbow- 3 lever 3 In the abovementioned patent, No. 181,258, the elbow-lever i and its connection by the rod z" and eccentric k, is clearly described, and is fully shown in Fig. 2 of the said patent. I

-, will therefore in this specification not reiterate the objeot of said elbow-lever and of its connection by the rod 1' with the vibrator B,

but will simply state that in the present invention I make the rod or strap t" self-adj ust- 5o ingl It is more fully shown in Fig. 7 of the accompanying drawings. 7 From this figure it will appear that the strap or rod 1 is made in two secti0nsan upper section, 15, which is rigidly attached to the strap which embraces the eccentric 7c, and a lower section, 16, which is pivotally connected with the elbow '6 To the section 15 is attached a box, 17, into which the section 16 enters, and which box containsa spring, 18, that bears at each end against shoulders within the box, and also at each end against collars 19, that are formed on the section 16, so that whether the strain or obstruction on the vibrator B may tend to shorten the connection between the elbow i and the eccentric 70 or to lengthen it, in either case the spring 18 will be compressed, and will allow the parts to yield to the obstruction; hence if, by a scrap of iron or other obstruction, the Vibrator should become clogged so that it cannot get its full stroke, the connections between the vibrator and the eccentric 7c would not be wrenched out of shape, nor would the vibrator itself be injured by such an obstruction.

I will now describe the third feature. of the present invention, which relates to improvement in mechanism for turning the ratchetwheel 1 2 3.

As already stated,the difficultyin the former patent, No. 181,258, with the mechanism for so turning the ratchet-wheel that it should set the vibrator in motion, was that the T-shaped piece 10 was not certain at all times to be reached by the plate 9 9 if the side motion of the vibrator should at any time be less than the normal toward the piece 10. In the present construction, in lieuof the pieces 9 and 10 of the old patent, I use a lever, X, which I pivot'by a pin, a, to one side of the vibrator B, and which lever on the outer side of the vibrator carries rigidly attached to its pivotpin an arm, Z)", having an outwardly-projecting tooth, 0 (See Figs. 10, 11, and 12.) This tooth enters a fork, d, which is attached to a lever, X, that is pivoted to the framing of the machine, said lever being connected to the pusher-bar 12, which is to move the ratchetwheel 1 2 3. This pusher-bar 12 in the present specification is intended to perform the same function as the pusher-bar 12 that is de scribed in Patent No. 181,258.

The lever X, which is pivoted, as described, to the side of the vibrator, and the form of which is indicated by dotted lines in Fig. 11, has a shorter arm, 6", in front and a longer arm, f at the back. Whenever the nipperslide H moves backward to get a new plate, or for any other purpose, it brings a cam, g which it carries under the longer armf of the lever X, and, lifting the same, tilts the projection I) and tooth 0 so as to move the lever Y in the direction of the arrow 1 in Fig. 10, thereby taking the pusher-bar 12 back off the ratchetwheel and putting it in position for imparting motion to said ratchet-wheel,whieh is the position shown in Fig. 1. When,afterward, the nipper-slide moves forward, it is intended that it should lift the short arm 6 of the lever X. To enable this to be done alever, Z, is pivoted at h to the nipper-slide, and overhangs a pin, j, that projects from the side of the upper nipper-jaw, n. Whenever the nippers engage a plate, so that the biting end of the jaw nis lowered, the pin h ,which is located back of the pivot k of the nippers, will be raised, and being beneath the lever Z will lift the same, so that during the forward motion of the nipper-slide and its attachments this lifter-lever Z will get under an enlargement, 12, of the arm e of the lever X, thereby raising said arm 6" and tilting the parts I) and so as to move the lever Y in the direction of the arrow 2, Fig. l0,thereby causing the push er-bar 12 to turn the ratchet-wheel l 2 3 sufficiently far to cause it to affect the lever 0, which lever 0 performs its functions as described with reference to the lever o in Letters Patent No.

181,258, and thus set the vibrator in motion. The vibrator, when the nipper slide has reached its lowermost position, which is its extreme front positionthat is to say, when the nail-plate has been cut up into nail-blanks causes its pawl y (which is the same as the pawl y described in Patent No. 181,258) to turn the ratchet-wheel 1 2 3 still further, so as to cause the said ratchet-wheel to set the clutch in engagement with the pinion d, and at the same time, by acting on the lever 0, stop the motion of the vibrator.

I will now proceed to the fourth part of the invention, which has reference to the motion that is imparted to the headers, which cause the nail-blanks to be headed.

Heretofore headers in nail-machines have been attached to pivoted arms that carry them in such a way as to cause them to join in the curvilinear motion. Such curvilinearmotion, however, is objectionable in the headers,-because it throws the head of the nail to one side. The object of this part of the present invention is to impart to the header a horizontal rectilinear motion. For this purpose the headers D 1), (see Figs. 5 and 6,) which are steel rods of suitable size,are placed in socketpieces E E or tubes, which are provided with shoulders 19 and q (see Fig. 5) or analogous projections. Each socket-piece E is set between two projecting ribs, 1' r, of the headinglever F. The upper face of this headinglever is rounded, as appears in Fig. 6, where it bears against the under side of the socket E.

The drivingshaft G (see Fig. 2) moves the cutter-lever l and thepivotJ thereofthat is, the pivot J turns,together with the cutter-lever I, in its appropriate bearings. This pivot J carries a cam or projection, 8, (see Fig. 4,) which engages under the upper beak of a double hook, L, the lower beak of which hook bears against the under side of the heading lever F. (See Fig. 6.) Thus whenever the pivot J is turned so as to lift the projection s, the heading-lever F will be swung up and inward on its own pivot, and will thereby move the header which it carries. If this header were rigidly attached to the headinglever F, as has heretofore been the case, its motion would be the objectionable curvilinear motion; but by attaching the header to the socket E, which rests loosely on the headinglever, and by at the same time guiding the in ner end of the header in a perforated portion, 25, of the stationary frame M of the machine, the result is that the motion of the header will be transversely horizontal and not curvilinear. Each machine may have only one header or two headers, two being shown in Fig. 6. The nail-blanks that are being headed are held in suitable dies, N.

Figs. 8 and 4 show that the upper beak of the double hook L, where it rests on the cam s, has a ball projection, a, which enters a corresponding ball-socket of the projection s. This allows of the conjoint use of the parts .9 and L, so that the rotary motion of the cam s will not interfere unduly with the upward motion of the hook L.

I claim 1. In a nail-maehine, the combination of the shaft A with the clutch O and loose pinion cl, the clutch 0 being constructed of the rings (6 and b, spring f, pivoted pawl h, and supporting projection m, and the pinion d, having tooth Z, substantially as described.
